SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No4-34,064, dated August 12, 1890.

Application tiled December 20, 1889. Serial No. 334,366. (No model.)

T0 all whom it may concern:

Beit known that I, JOHN IsELE, a citizen of the United States, residing at San Diego, in the county ofSan Diego and State of California, have invented certain new and useful Improvements in Spring-Motors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention has relation to spring-motors for blacksmiths fans, ohurns, and light Inachinery generally; and the object is to produce a device of this kind that will be simpleI and cheap in construction, eifective in operation, and easily controlled or governed as to speed; and to these ends the novelty consists in the construction, combination, and arrange- Inent of part-s of the same, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings, the same letters of reference indicate the same parts of the invention.

Figure 1 is a side elevation of my improved motor as it appears attached to and operating a blacksmiths fan. Fig. 2 is a detached perspective View of the regulating-governor, and means for insuring a regular motion of the same when the motor is placed on an unstable base-as, for example, on a car or in a boat. Fig. 3 is a side elevation of the governing mechanism, and Figs. et and 5 are details of the governor-operating device.

A represents the front portion of the framework, and it may be of any suitable size and shape to correspond to the size of the motor and the work to which it is to be applied.

B is a spring secured to and surrounding shaft B', which spring may be wound up by the crank C, and secured by the pawl a, spring b, and ratchet-wheel c.

C is a gear-wheel mounted on shaft B which meshes with a pinion c on the shaft c2, and said shaft is provided withl a gear D, meshing with a pinion d on the shaft 0l. This shaft has a gear E meshing with a pinion e on the shaft e', and this shaft has a gear F Ineshing with a pinion f on its shaft f. The shaft f has a gear H operatinga pinion hon the shaft h', which operates the fan J, the Whole constituting an ordinary train of gearing, so that when the spring B is wound up a very rapid motion will be imparted to the fan J.

L is anordinary cut-o valve in the pipe L,leading from the fan, whereby the amount or force of the air passing through the pipe L may be conveniently regulated, and m is a door whereby access may be had to the interior of the fan when necessary.

N is a governor or pendulum mounted so as to swing freely upon a stud n, its upper end being provided with a slot n', in which works a pin o, adjustably secured in a slot O in a face-plate P, secured to the shaft o2, so that as the shaft o2 rotates an oscillating or swinging motion will be imparted to the pendf ulum N. l

R is a weight provided with a guide @which allows said weight to be freely adjusted up and down the lower portion of the pendulum.

S is a iiexible cord secured to the pendulumweight and having its upper end wound around a sleeve s upon the stud n. This sleeve is provided with a ratchet-wheel T and a pawl t, secured to the pendulum N, which serves to retain the ratchet at any d esired point, and itis obvious that by turning the wheel T the weight R may be raised or lowered to any desired point. When the spring is wound up, motion is imparted to the pendulum and the speed of the gearing regulated by raising or lowering the weight. Of course the nearer the weight is to the fulcrum the faster the speed, and the farther away from it the slower the machine will run.

By means of the slot O in the face-plate P and the adjustable pin o the degree of oscillation,or,the are through which it swings, may be increased or diminished, and consequently the speed by this means may also be regulated to a nicety. y

Vhen the motor is intended for use on a car or boat, I provide a roller or anti-friction wheel u on the lower end of the pendulum, and this roller Works in an arc-shaped guide U, so that a lateral oscillation of the frame will ynot affect the motion of the pendulum. Of course the number, length, and thickness IOO v of the mainsprings employed Will be Varied ratchet-wheel T, sleeve s, pawl t, oord S, and the adjustable Weight R, substantially as described.

2. The combination, With themainspring and train of gearing, of the pendulum N, provided With the roller u, and the are-shaped guideU, substantially as shown an d described.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN ISELE.
